2 Introduction

Microsemi’s Evaluation Board PD-IM-7508 provides the designer with the environment to evaluate the performance and the implementation of 8-port Power over Ethernet (PoE), based on Microsemi’s PoE Devices (PD39100 & PD69108). Evaluation Board assists Switch designers to evaluate an IEEE- 802.3af-2003 and IEEE802.3at-2009PoE based solution, with maximum flexibility and ease in configuration. Microsemi’s PD69108 is a 8-port, mix-signal, high-voltage Power over Ethernet (PoE) Manager designed to support IEEE- 802.3af-2003 and IEEE802.3at-2009 PoE applications.

2.1 Hardware Block Diagram Description

The block diagram shown in Figure 2 illustrates the 8-port Evaluation Board. A single PD39100 microcontroller unit (PoE Controller) is connected to a single PD69108 PoE device. As shown in the figure, the PoE Controller controls and monitors the PoE device using an isolated ESPI bus. Communication with PoE controller is done by a serial communication interface (UART by USB). EVB can be powerd by an external power supply or by another 4pairs PSE port.

3.1 Switches

Evaluation system comprises switches used to select the desired configuration states of the board.

3.1.1 Reset Button

The dedicated Reset push button SW1 (see Figure 3) resets PoE controller PD39100.

Figure 3: Reset Push Button (SW1)

3.1.2 Power Good Dip Switch

The dedicated Power Good dip switch SW2 (see Figure 4) sets the Power Good pins of the PD69108. This will allow the user to select one of the available 16 Power Banks.

Note: if the EVB is powered up by a PD port, the Power Bank is automatically set to Bank #2.
